    30 * Instance of TXmlEngBinaryContainer class represents binary data in 

    31 * DOM tree.

    32 *

    33 * Binary data is treated in general as text nodes in DOM tree. 

    34 * Some of the fields in xmlNode structure are reused in order to save memory. 

    35 * Data is stored in process's heap memory.

    36 *

    37 * Sample code for creating binary container:

    38 * @code  

    39 *      RXmlEngDOMImplementation domImpl;

    40 *      domImpl.OpenL();        ///< opening DOM implementation object 

    41 *      RXmlEngDocument iDoc; 

    42 *      ///< create document element

    43 *      TXmlEngElement elem = iDoc.CreateDocumentElementL(_L8("doc"));

    44 *      ///< create binary container from buffer (str1) and CID equals cid

    45 *      TXmlEngBinaryContainer binData=iDoc.CreateBinaryContainerL(cid,*str1);  

    46 *      elem.AppendChildL(binData);      ///< append container to the dom tree       

    47 *      iDoc.Close();               ///< closing all opened objects

    48 *      domImpl.Close();

    49 * @endcode
